Fast, Reliable General Contractor Across Bostonia
Hiring a General Contractor in Bostonia means dealing with San Diego County permits, not El Cajon’s city hall. That distinction changes timelines, paperwork, and cost. Our crews work Bostonia lots every week, from the ranch homes along Winter Gardens Boulevard to the larger acreage properties off Pepper Drive. We know what the county will flag before you spend a dollar on drawings. Call (619) 604-9624 and we’ll walk the property with you.
Why Penhallow Remodeling San Diego Is Bostonia’s Preferred General Contractor Company

Bostonia homeowners call us because we write the price down before we pick up a hammer. Not a range on a napkin. A written number you can hold us to. Trevor Nash started this company around one belief: the number on day one is the number on the final invoice. No change orders hiding behind demo day discoveries, because we scope the job correctly up front.
We also answer the phone. A real person, 24/7. No voicemail maze when you’re standing in a torn-up kitchen wondering when the county inspector is coming. That alone separates us from most contractors working Bostonia acreage jobs.
Every technician who steps onto your property is background-checked and arrives in uniform. You know exactly who is walking through your gate. And our 365-Day Done Right Promise is in writing on every project: if the work fails inside the guarantee period, we come back and fix it at no charge.
Styles & brands we work with







Remodeling Contractor in Bostonia
A Remodeling Contractor in Bostonia handles kitchens, bathrooms, and whole-home reconfigurations, and the work here almost always runs through the County of San Diego Planning & Development Services rather than a city planning desk. For unincorporated Bostonia, that means plan checks and inspection sign-off typically add 2 to 4 weeks compared with a job across the city line in El Cajon. Kitchen remodels in Bostonia run $16,520 to $53,100 depending on layout, cabinet line, and countertop material. Bathroom remodels run $10,620 to $33,040.
Kitchen and Bath Scope
Most Bostonia homes were built between the 1950s and 1980s, so original plumbing stacks, galvanized supply lines, and undersized circuits show up the moment we open a wall. That’s why we quote the rough-in work first. You’ll see the real number before demo starts, not after.
Finishes and Trade Brands
We install KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler or Moen fixtures. These brands carry their own warranties alongside ours, which matters when you’re spending five figures on a Bostonia remodel.
Licensed General Contractor in Bostonia

A Licensed General Contractor in Bostonia pulls the permits, schedules the inspections, and coordinates every trade, and here that job includes county-specific work El Cajon residents never see: septic and well setback reviews, grading checks, and access planning for long or unpaved driveways. Home additions in Bostonia run $53,100 to $153,400. Detached ADUs run $106,200 to $259,600. The county process alone can add weeks, which is exactly why you want a contractor who has done it before.
Permit and Setback Work
We pull every permit and stand with you through every inspection. On acreage lots, the county reviews septic leach field distances and well clearances before approving a building pad. That review can force a placement change you never saw coming if the contractor didn’t check first.
Scope Before Quote
We scope county requirements before we quote. That means checking panel capacity, driveway access for concrete trucks, and where the leach field sits relative to your proposed addition. You get a written price that reflects Bostonia reality, not a neighboring city’s numbers.
Trusted Brands We Service in Bostonia
We source materials from brands that hold up on unincorporated lots: James Hardie siding for dry heat and wet winters, KraftMaid cabinetry for kitchens, and Tuff Shed for detached storage structures when an ADU isn’t in the budget. Our Bostonia customers get the same live 24/7 phone coverage and same written guarantee no matter which product line fits their project.

AfterCommon General Contractor Problems We See in Bostonia Homes
- 100-amp electrical panels. Many Bostonia homes still run original 100-amp service. Adding central air or an ADU subpanel means upgrading the service entrance, and that’s a county-inspected job we fold into the quote.
- Septic and well setbacks on acreage. A homeowner wants a detached shop or ADU, then the county flags the leach field distance. The building pad moves 30 feet and the schedule shifts. We check this before quoting.
- Stucco cracking from thermal movement. Bostonia’s hot, dry summers and mild, wet winters cause expansion and contraction that opens hairline cracks in older stucco. We address the substrate, not just the surface patch.
- Long unpaved driveways and equipment staging. Concrete pumps and dump trucks can’t always reach the pour site on larger lots. Off-road staging and extended chute work add cost that a city contractor might never mention.

FAQs About General Contractor in Bostonia
Every permit goes through the County of San Diego Planning & Development Services instead of a municipal building department. Plan checks, septic and well reviews, and inspection sign-off typically add 2 to 4 weeks and require more documentation than a job in El Cajon. We manage that paperwork for you and build the timeline into the written quote. Call (619) 604-9624 to get your project scoped with the county process accounted for.
Yes. Detached structures on unincorporated Bostonia lots require county permits, including septic and well clearance reviews. Skip the permit and you may be forced to remove or relocate the structure later. We pull the permits, coordinate the county inspections, and include that work in the written price. Need to know if your lot can support a detached ADU? Call (619) 604-9624 and we’ll check setbacks before you commit.
Because most Bostonia homes still have original 100-amp panels, and once you add central air, an ADU, or modern kitchen appliances, the service entrance can’t keep up. The county requires the upgrade to meet current National Electrical Code before it signs off. We fold the panel swap into the remodel quote so there’s no surprise invoice later. For a written number that includes the panel, call (619) 604-9624.
The county measures the distance from your proposed building pad to the septic leach field and the well head. If the addition sits too close, the pad must shift, sometimes 30 feet or more. A contractor who quotes before checking these setbacks is handing you a change order waiting to happen. We verify setbacks before we quote. To find out what’s buildable on your lot, call (619) 604-9624.
Open lots in Bostonia typically need a grading plan and drainage review before any concrete pour. The county wants to see where storm water goes, especially on sloped acreage. We handle the grading plan, schedule the county review, and write the real number for site prep before the first truck arrives. Ready to see the full cost on paper? Call (619) 604-9624 for a free estimate.
